BICYCLE PUMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 606,023, dated June21,1898.

Application filed July 8, 1897. Serial No. 643,828. (No model.)

To all whom it may concern:

Be it known that I, LEWIS A. PAYNE, a citizen of the United States,residing at San J os,

county of Santa Clara, State of California, have invented an Improvementin'Bicycle Pump Attachments; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to a pump attachment for bicycles which is adaptedto be so ad justed as to be operated from the seat-post and providedwith connections whereby air can be introduced to the pneumatic tires ofeither of the wheels without the use of a supplemental pump.

It consists in details of construction which will be more fullyexplained by reference to p the accompanying drawings, in which-- Figure1 is a sectional view of the saddle post and connections. Fig. 2 is adetail of the slidable standard.

A is the seat-post or standard of the bicycleframe, the other portionsof the frame being essentially similar to those in ordinary use. WVithinthis part of the frame is the tubular slidable seat-post or standard B,which is adapted to be moved up and down to adjust the height of thesaddle for the rider, and when thus adjusted it is secured firmly bymeans of a clamp O. \Vithin this tubular adj ustable post is an interiortube D, which is slidable within the adjustable part B and has its lowerend fitted with a suitable plunger E, which is adapted to form a tightjoint with the interior of the tube A when the part D is moved downwardand which may have a valve or will yieldin the usual manner of suchplungers' to allow air to be admitted from above, thus acting whenreciprocated as a force-pump.

The saddle itself is fixed in the usual or any suitable manner upon thetop of the post D, and the part B is grooved or channeled, as shown atb, so that when the transverse bar F, which carries the saddle, has beenforced down close to the part B this bar fits into the fore-andaftchannel I) and thus holds the seat firmly in place, the adjustment, asbe-- fore stated, having been made by raising or lowering the part B.

The upper part of D is made slightly larger or tapering enough so thatit will bind and remain solidly in place in the socket b, but can beeasily withdrawn when the device is .to be used as a pump.

p The flexible connecting-tube J is adapted to have one end screwed uponthe end of the tube I, and the other end is arranged to be connectedwith the inlet-valve openings of either of the tires upon the wheels ofthe machine, and when this connection has been completed it is onlynecessary to reciprocate the plunger D and compress the air within thestandard or post A, when it will be conducted through the passage H andthe tube J to the proper point.

At one side of the tube D is made an opening d of sufficient size toallow the flexible tube J to be inserted when not in use to connect withthe tires. The work of pumping having been completed, it is onlynecessary to disconnect the tube J and insert it into the opening d,when it will lie within the plunger-tube D and be entirely protected.

My device is very convenient, gives a strong pump of large capacity, sothat the work of pumping can be rapidly completed, and when the partsare not in use they are still a portion of the machine and always withineasy reach for use.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the seat post standard of a bicycle-frame, of averticallyadjustable tubular seat-support, a clamp by which it may beheld at any desired point, a supplemental interior tube having the upperend fitted to receive and hold the saddle and the lower end providedwith an air-forcing plunger whereby the reciprocation of this tube willcompress air within the seat-post standard, a tubular connection curvingaround the crank-hanger bearing with a connecting-nipple, and a flexibletube adapted to connect plunger having the approximately-horizontalseat-bar at its upper end, said bar being adapted to fit snugly in thechannel at the upper end of the adjustable tubular portion whereby thesaddle is held rigidly in place when the pump is not in operation.

3. The combination with the seat-post 20 standard of a bicycle-frame ofan interior tubularadjustable post with a clamp whereby it may be heldin position, a hollow plungerrod slidable within said adjustable posthaving the lower end adapted to compress air in the lower part of theseat-post standard and the upper end carrying the saddle-support in gbar with means for locking the whole together, and an opening in theside of the plunger-tube with a chamber wherein the flexibleconnecting-tube is stored when not in use.

In witness whereof I have hereunto set my hand.

. LEW'IS-A. PAYNE.
